62969  23 
* Simplified outer syntax: uniform category "name" includes long 
24 
identifiers. Former "xname" / "nameref" / "name reference" has been 

25 
discontinued. 

26 

62807  27 
* Mixfix annotations support general block properties, with syntax 
28 
"(\<open>x=a y=b z \<dots>\<close>". Notable property names are "indent", "consistent", 

29 
"unbreakable", "markup". The existing notation "(DIGITS" is equivalent 

30 
to "(\<open>indent=DIGITS\<close>". The former notation "(00" for unbreakable blocks 

31 
is superseded by "(\<open>unbreabable\<close>"  rare INCOMPATIBILITY. 

62789  32 

62440  33 
* New symbol \<circle>, e.g. for temporal operator. 
34 

62453  35 
* Old 'header' command is no longer supported (legacy since 
36 
Isabelle2015). 

37 

63273  38 
* Command 'bundle' provides a local theory target to define a bundle 
39 
from the body of specification commands (such as 'declare', 

40 
'declaration', 'notation', 'lemmas', 'lemma'). For example: 

41 

42 
bundle foo 

43 
begin 

44 
declare a [simp] 

45 
declare b [intro] 

46 
end 

63272  47 

63282  48 
* Command 'unbundle' is like 'include', but works within a local theory 
49 
context. Unlike "context includes ... begin", the effect of 'unbundle' 

50 
on the target context persists, until different declarations are given. 

51 

63383  52 
* Proof method "blast" is more robust wrt. corner cases of Pure 
53 
statements without objectlogic judgment.

62440  55 

62904  56 
*** Prover IDE  Isabelle/Scala/jEdit *** 
57 

63135  58 
* Cartouche abbreviations work both for " and ` to accomodate typical 
59 
situations where old ASCII notation may be updated. 

60 

63022  61 
* IDE support for the Isabelle/Pure bootstrap process, with the 
62 
following independent stages: 

63 

64 
src/Pure/ROOT0.ML 

65 
src/Pure/ROOT.ML 

66 
src/Pure/Pure.thy 

67 
src/Pure/ML_Bootstrap.thy 

68 

69 
The ML ROOT files act like quasitheories in the context of theory 

70 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

71 
The theory files are presented with a modified header to import Pure 

72 
from the running Isabelle instance. Results from changed versions of 

73 
each stage are *not* propagated to the next stage, and isolated from the 

74 
actual Isabelle/Pure that runs the IDE itself. The sequential 

63307  75 
dependencies of the above files are only observed for batch build.

* The defining position of a literal fact \<open>prop\<close> is maintained more

111 

112 
* Commands 'finally' and 'ultimately' used to expose the result as

optional abstraction over local parameters. The syntax resembles 

63043  132 
'definition' and 'obtain'. It fits better into the Isar language than

Isabelle2016). INCOMPATIBILITY, use "standard" instead. 

143 

63259  144 
* Proof methods may refer to the main facts via the dynamic fact 
145 
"method_facts". This is particularly useful for Eisbach method 

146 
definitions. 

147 

63527  148 
* Proof method "use" allows to modify the main facts of a given method 
149 
expression, e.g. 

63259  150 

151 
(use facts in simp) 

152

730

The local assumptions are bound to the name "that". The result is

corresponds to a raw proof block like this:

61733  890 
* Assumptions ('assume', 'presume') allow structured rule statements 
891 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  892 

893 
assume result: "C x y" 

894 
if "A x" and "B y" 

895 
for x :: 'a and y :: 'a 

896 

897 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

898 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

899 

900 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

901 
only effects propositions according to actual use of variables. For 

902 
example: 

903 

904 
assume "A x" and "B y" for x and y 

905 

906 
is equivalent to: 

907 

908 
assume "\<And>x. A x" and "\<And>y. B y" 

909 

60595  910 
* The meaning of 'show' with Pure rule statements has changed: premises 
911 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  912 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
913 
follows: 

60595  914 

915 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

916 

917 
or: 

918 

919 
show "C x" if "A x" "B x" for x 

920 

921 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

922 

923 
show "C x" when "A x" "B x" for x 

924 

60459  925 
* New command 'consider' states rules for generalized elimination and 
926 
case splitting. This is like a toplevel statement "theorem obtains" used 

927 
within a proof body; or like a multibranch 'obtain' without activation 

928 
of the local context elements yet. 

929 

60455  930 
* Proof method "cases" allows to specify the rule as first entry of 
931 
chained facts. This is particularly useful with 'consider': 

932 

933 
consider (a) A  (b) B  (c) C <proof> 

934 
then have something 

935 
proof cases 

936 
case a 

937 
then show ?thesis <proof> 

938 
next 

939 
case b 

940 
then show ?thesis <proof> 

941 
next 

942 
case c 

943 
then show ?thesis <proof> 

944 
qed 

945 

60565  946 
* Command 'case' allows fact name and attribute specification like this: 
947 

948 
case a: (c xs) 

949 
case a [attributes]: (c xs) 

950 

951 
Facts that are introduced by invoking the case context are uniformly 

952 
qualified by "a"; the same name is used for the cumulative fact. The old 

953 
form "case (c xs) [attributes]" is no longer supported. Rare 

954 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

955 
and always put attributes in front.

* Nesting of Isar goal structure has been clarified: the context after 
963 
the initial backwards refinement is retained for the whole proof, within 

964 
all its context sections (as indicated via 'next'). This is e.g. 

965 
relevant for 'using', 'including', 'supply':

* Command 'obtain' binds term abbreviations (via 'is' patterns) in the 

976 
proof body as well, abstracted over relevant parameters. 

977 

978 
* Improved typeinference for theorem statement 'obtains': separate 

979 
parameter scope for of each clause. 

980 

981 
* Term abbreviations via 'is' patterns also work for schematic 

982 
statements: result is abstracted over unknowns. 

983 

60631  984 
* Command 'subgoal' allows to impose some structure on backward 
985 
refinements, to avoid proof scripts degenerating into long of 'apply' 

986 
sequences. Further explanations and examples are given in the isarref 

987 
manual.

60617  1017 
is marked as legacy, and will be removed eventually. The proof method 
1018 
"goals" achieves a similar effect within regular Isar; often it can be

'abbreviation' is also kept for morphims that only change the involved

1043

account. Type definitions with open dependencies on overloaded 

1089 
definitions need to be specified as "typedef (overloaded)". This

* Qualification of various formal entities in the libraries is done more 

1093 
uniformly via "context begin qualified definition ... end" instead of 

1094 
oldstyle "hide_const (open) ...". Consequently, both the defined 

1095

1127 

1128 
* The alternative notation "\<Colon>" for type and sort constraints has been 

1129 
removed: in LaTeX document output it looks the same as "::". 

1130 
INCOMPATIBILITY, use plain "::" instead. 

1131 

1132 
* Commands 'inductive' and 'inductive_set' work better when names for 

1133 
intro rules are omitted: the "cases" and "induct" rules no longer 

1134 
declare empty case_names, but no case_names at all. This allows to use 

1135 
numbered cases in proofs, without requiring method "goal_cases". 

1136 

1137 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

1138 
lowlevel facts of the internal construction only if the option 

62093  1139 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  1140 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
1141 

1142 
* Recursive function definitions ('fun', 'function', 'partial_function') 

1143 
expose lowlevel facts of the internal construction only if the option 

62205  1144

* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

1148 
of the internal construction only if the option "bnf_internals" is

* The coercions to type 'real' have been reorganised. The function 

1202 
'real' is no longer overloaded, but has type 'nat => real' and 

1203 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

1204 
abbreviates of_int for that type. Other overloaded instances of 'real' 

1205 
have been replaced by 'real_of_ereal' and 'real_of_float'.
